My y400 was working fine this morning, then suddenly shut down. When I try to restart; the keyboard lights up and fan hits high RPMs for about 10 seconds and then the machine shuts off. Same result with the "novo" button.
Guys at geek squad says it sounds like a bad motherboard.
3 months out of warrenty.
